How is the remainder calculated in Java?

In Java, the modulo operation is performed using the % symbol. Modulo refers to the operation of dividing one number by another and returning the remainder of the division.

The rule for the modulo operation is as follows:

1. If both the dividend and the divisor are integers, the modulo operation will return an integer, indicating the remainder of the division of the two numbers.
2. If either the dividend or divisor is a floating point number, the modulus operation will return a floating point number that represents the remainder of dividing the two numbers.

Here are some examples:

int a = 10;
int b = 3;
int result = a % b; // result的值为1，因为10除以3的余数是1

double c = 10.5;
double d = 3.2;
double result2 = c % d; // result2的值为1.1，因为10.5除以3.2的余数是1.1

It should be noted that the sign of the remainder obtained from the modulo operation will be the same as the sign of the dividend. For example, if the dividend is negative, the remainder obtained from the modulo operation will also be negative.

int e = -10;
int f = 3;
int result3 = e % f; // result3的值为-1，因为-10除以3的余数是-1
